SOLE FOB FOOTWEAR.

Speoication of Letters Patent.

Patented Dec. 4, 1917.

Application filed October 21, 1916. Serial No. 128,929.

To all whom it may concern:

Be it known that I, MIRIAM E. BENJAMIN, a citizen of the United States,residing at Washington, in the District of Columbia,

have invented new and useful Improvements in Soles for Footwear, ofwhich the following is a specification.

This invention has for its object to provide an article of footwear theinnersole of which is adapted to contain, between its bottom and topsurfaces, powdered material such as sulfur, and to expose portions ofsaid material at the up er surface of the sole, the powdered materialbeing intended to prevent certain diseases and ailments, to aid inkeeping the feet warm, and to promote the circulation of the blood.

The invention is embodied in the improvements which I will now proceedto describe and claim.

Of the accompan ing drawings, forming a part of this speci cation,-

Figure 1 represents a longitudinal section of a shoe embodying myinvention.

Fig. 2 represents a top plan view of the innersole, s own by Fig. 1,removed from the shoe.

rF ig. 3 represents a view similar to Fig. 1, showing a modification.

The same reference characters indicate the same parts in all of thefigures.

In the drawings,-

a represents the outer sole and b the upper y of a shoe which may be ofany suitable construction. The sole embodying my invention is :formedpreferably at its fore portion only,

as a pouch Iadapted to contain powdered lmaterial such as sulfur,although various other powdered materials may be employed. I'I he upperside of the pouch is pervious to said powder so that the latter may Iindits y way to the bottom of the wearers foot.

,I make the sole by marginally uniting a sole-shaped bottom layer 3 anda sole-shaped top layer 2 by means such as stitches 8. The

fore portions of said layers constitute a A pouch adapted to contain acharge 7' of powdered material. The bottom layer 3, which is continuousand of material impervious to moisture, such as rubberized cloth,protects the charge 7 from an dampness which may enter the bottom of t eshoe. The top layer 2 is also of material impervious to moisture, suchas rubberized cloth, and is cut away at intervals .to form openings 5adapted to expose portions of the charge 7. The impervioiis material ofthe top layer 2, excludes moisture from the foot from the portions ofthe charge covered by the top layer, so that said portions remain dryand free to shift. laterally to the openings 5, to replaceportion'sescaping through the openings. An additional elongated opening9 is provided through which the, charge may be inserted and the sole maybe introverted, cleansed and refilled. 6 represents a cushioning layer of elastic rubber attached to the rear portions of the innersole andeither interposed between the layers as shown by Fig. 1 or superimposedon said layers as shown by Fifr. 3 with or without attachment thereto.'he sole may be permanently attached to the shoe, or may be insertedloosely therein.

I claim 1. A sole for footwear comprising marginally connected top andbottom layers forming a pouch, and a charge of powder inserted in saidpouch, the bottom layer being impervious to moisture penetrating thebottom of the shoe of which said sole forms a part, while the top layeris also of material impervious to moisture, and is cut away at intervalsto form openings exposing portions of said charge, other portions of thecharge being protected 'from moisture by the material of the top layer.

2. A sole for footwear comprising marginally connected top and bottomlayers forming a pouch, and a charge of powder inserted in said pouch,the bottom layer being impervious to moisture penetrating the bottom ofthe shoe of which said sole forms a part, while the top layer is also ofmaterial impervious to moisture, and is cut away at intervals to formopenings exposing portions of said charge, other portions of the chargebeing protected from moisture by the material of the to layer, one ofthe layers being provided with a slit therein through 100 which the solemay be introverted for the purpose of cleansing and through which thesole may be refilled.

3. An introvertible sole for footwear com- 5 prisng marginally connectedtop and bottom layers forming a pouch, adapted to contain a charge ofpowder, the top layer being ings being formed to permit the sole w be.

turned inside out.

1n testimony whereof I have affixed my signatu re.

MRT AM E. BENJAMIN.
